Year-band analysis

Best year to buy. Worst to avoid.

First-time MOT pass rate split by registration band. Pass rates barely move across bands here, so the year you buy Volvo Xc40 R Design B4 Mhev Auto makes little measurable difference to MOT outcomes.

Best band to buy

94.9%

2018–2020 registration

the 2018–2020 band climbs to 94.9% — a 0.9-point improvement. Failures here are mostly wear items: has a cut in excess of the…, less than 1.5 mm thick — the structural issues that drag down older examples don't appear in the top-10 for this band.

Band to be cautious about

93.9%

2021+ registration

On the 2021-on band, the data shows a 93.9% pass rate against a fleet average of 94.9% on the newer band. The main culprits logged at test: damaged but not adversely affecting driver's view, blade defective, and tread depth below requirements of 1.6mm. Average mileage on test for this band is 27,036 miles — high-mileage wear items are a recurring theme.

Best band to buy: 2018-2020 (94.9% first-time pass). Worst band to avoid: 2021+ (93.9% pass). That's a 0.9-point spread across 1,965 older tests and 979 newer ones — year of build makes a material difference on this model.
